Requirement for PST on Professional Services - How does this affect Building Designers?
The British Columbia government has officially paused its planned expansion of the Provincial Sales Tax (PST) to professional services, offering a major sigh of relief to the province’s design and construction sectors. Originally scheduled to take effect on October 1, 2026, the new rules would have applied PST to architectural, engineering, and accounting services, among others. However, citing international trade uncertainty and broader economic disruptions, Premier David Eby announced a temporary regulation to delay the rollout. This means that architectural services will remain exempt from PST for the foreseeable future, sparing businesses and clients from immediate fee increases and administrative changes as the province monitors global economic stability.
This pause provides dual clarity for the design sector, especially regarding how the province defines taxable activities. Under the proposed framework, "architectural services" are strictly defined as advice or work provided by a professional who is registered or required to be registered with the Architectural Institute of British Columbia (AIBC) under the Professional Governance Act. Because of this two-tier criteria, building designers who operate outside of AIBC registration requirements are entirely exempt from charging this tax. If a designer does not meet the legal threshold requiring AIBC registration, their design, planning, or construction review work does not qualify as an "architectural service" for PST purposes. Consequently, independent building designers and their clients can rest assured that their services remain safely outside the scope of the tax, regardless of future pauses or rollouts.
